Cattle are transported multiple times throughout their lifespan due to the geographic distribution of the United States beef industry. However, transportation can elicit a variety of stressors that jeopardize cattle growth performance and health.
Wagyu-sired steers and heifers (WA) from two different sires, selected for either growth (G) or marbling (M), and Angus-sired steers (AN) were fed for a similar days on feed (D) or to a similar final body weight (B) in two independent experiments. In…
Inclusion of corn grain in cattle diets increases the dietary concentration of unsaturated fatty acids like linoleic acid. Ethanol co-products are most often made from corn grain in the United States and contain concentrated amounts of unsaturated fatty…
Livestock producers have an opportunity to improve sustainably through the utilization of co-products of the bio-fuel industry through cattle feeding. Crude glycerin, although less commonly fed compared to distillers grains, provides an opportunity for…
Although in vitro data with mixed ruminal fluid demonstrated positive effects of postbiotics from lactobacilli on measures of fermentation and microbial profiles, there is a paucity of in vivo data with lactating ruminants. We evaluated the effects of…
The inclusion level of wheat in poultry feeds is limited by nonstarch polysaccharides (NSP). Feeding NSP will increase the intestinal viscosity and residence time of the digesta, reduce nutrient digestion, and absorption of nutrients by birds, thereby…
Gilt development feeding programs are important to ensure that the female grows at an appropriate rate, without becoming overconditioned or developing locomotion issues. Moreover, between 90 d of age and puberty is the first phase of rapid mammary…
Male sexual behavior is a key factor in reproduction, especially in seasonal breeders such as sheep. The identification of differentially expressed genes (DEGs) in brain regions involved in male reproduction and sexual behavior between rams with different…
This experiment evaluated the effects of dietary inclusion of hempseed cake or dried corn distillers grains plus solubles on ruminal fermentation parameters, organic matter (OM) intake, total tract nutrient digestion, and nitrogen (N) balance in steers…
The American Society of Animal Science is a membership society that supports the careers of scientists and animal producers in the United States and internationally. ASAS is a 501c3 Professional Membership Organization.
For over 100 years, ASAS broadened membership to more than 5000 members. We’ve developed diverse and dynamic membership programs, and fostered the growth of the premier journal in animal science and the premier animal science meetings.
About ASASMembership is open to individuals, organizations, or firms interested in research and application, instruction, or extension in animal science or associated with the production, processing, marketing, or distribution of livestock and livestock products.
